Intro

Surviving 10x 1K In The Aussie Heat | Brutal Threshold Workout! from Ben Is Running is solid viewing. Below is what you need to replicate the session yourself—check the full video for the rest of the context.

Key Points

• Threshold focus: The structure is straightforward: a 10‑minute run at LT1 (≈ 340‑341 s/km), then 10 × 1 km repeats at LT2 (≈ 310‑315 s/km).
• Heat adaptation: When it’s 24‑25 °C outside, heart‑rate climbs; base your effort on feel rather than sticking to strict splits.
• Recovery strategy: After the 10‑minute block, take a 3‑minute easy jog. Between each 1‑km repeat, stand for 60 seconds to recover.
• Training flexibility: On a trip? A single, longer LT2 session can substitute for a full double‑threshold day while keeping your weekly volume intact.

Workout Example

1. Warm‑up (if needed) – light jog.
2. Steady 10‑minute run at Lactate Threshold 1 (~340 s/km).
3. Rest: 3‑minute easy jog before the repeats.
4. 10 × 1 km repeats at Lactate Threshold 2 (~310‑315 s/km) with 60 seconds standing recovery between repeats.
5. Cool‑down – easy jog and stretching.

Tip: Heat demands a slower pace than your usual LT2—dial it back 5–10 s/km and check your heart‑rate to confirm you’re in the target zone.

Closing Note

Test this session out—dial in your paces with the Pacing app based on your fitness, then take it on. Good luck, and happy running into 2025!
